Application filed July 22, 1914. Serial No. 852,493.

devices for two separate tin cans disposed in known manner on the front side of the machine, in such a manner, that the two tin cans may be simultaneously seamed by the one roller.

A further feature of the present inven tion consists in the design of the driving gear for the automatic tin can feeding mech anism, so that the operations of this feed ing mechanism are in cooperative relation to those of the seaming and closing appliances.

Another novel feature of the present invention is the arrangement to engage and disengage the driving gear forthe seaming and closing mechanisms by means of a footv lever, so that the operator has his hands free for other purposes.

In the accompanying drawing two constructional forms of the present invention are exemplified.

Figure 1 is a front elevation of the machine, on the line 1I in Fig. 2. Fig. 2 is a plan of the machine. section on the line IIII in Fig. 2. Fig. 3 is a detail view, on an enlarged scale, of the clutch for controlling the driving gear for the seaming and closing mechanisms. Figs. &6 are plan diagrams showing the various periods of the operation of the seamingroller carrier. Fig. 7 is a plan of the second constructional form of the seaming roller carrier.

On the front side of the body 1 of the machine is arranged the plunger-like carrier 3 vertically slidable in a guide 2 and carries the two rotatable disks 1 and 5, onto which the tin cans 6 and 7 are, placed.

8 and 9 are the clamping disks, the axes 10 and 11 of which are revoluble in the bearings 12 and 13 respectively. The belt pulleys 141 and 15 fitted to the shafts 10 and Fig. 3 is a. vertical 11 respectively are coupled by belts 16 with the main driving shaft 17, which is fitted to the shaft 18.

19 is a cam disk, arranged on shaft 20 and driven from shaft 18 by means of the worm wheel 21, the worm-22 and the belt 23.

The seaming roller carrier 2 1 is slidably fitted in the bearing 25 of the machine body 1. At the rear end of the seamingroller carrier 24 is fitted a roller 26, which'bears against the cam disk 19,

26 is a spring which tends to press the seaming roller carriercontinuously against the cam disk. On the'seamingv roller carrier 2% is fitted the first seaming roller 27 and the flattening roller 28, or, according to the modification shown in Fig. 7, two each such rollers are provided. The seaming rollers are rotatably journaled in the known manner.

29 is a foot lever, which by means of the rod 30 of arm 31 and rod 32 will operate,

on the one hand on the plunger-like carrier 3, and on the other hand by means of lever 3 1 and rod 35 on the clutch 36, for engag- Y I it rotates constantly as it is driven by the worm 22 and the belt 23. The shaft 20 ro-' tates with the worm wheel 21 only when the members of the clutch 36 are engaged. The engaglng and disengaging of the clutch 36 takes place by moving to or fro the righthand member of the clutch on the shaft 20, (see Figs. 2 and 3) this member of the clutch rotating with the shaft 20. To accomplish this, the bar 35 is formed at its upper end as a frame 35 which straddles the shaft 20 and the right-hand member of the clutch, the frame 35 having on its righthand side (Fig. 3*) an inclined surface 35 adapted to bear against an inclined member 36 formed on a disk 36, the latter being formed in one piece with the right-hand member of the clutch 36. Cooperation of the inclined surfaces 35 and 36 causes the disk 36 and theright-hand member of the clutch 36 to be moved to the right in opposition to the action of the spring 36", thereby disengaging the clutch members. By stepping upon the pedal 29, the inclined surfaces above mentioned slide in a direction from one another and the spring 36 forces the right-hand member of the clutch 36 toward the left whereby the clutch members are engaged. The disk 36 has on its periphery a recess 36, and the frame *carlies a laterally projecting roller 35 which rests upon the periphery of the disk 36 After each revolution of the disk 36 the roller 35 drops into the recess 36, causing the inclined surfaces 35 and 36 to slide upon one another, thereby disengaging the clutch automatically before completion of the rotation of the disk 36*, if the pedal 29 is no longer depressed. On the latter is fitted a sprocket 36 which by means of the chain 37, the sprocket 38 and the gears 39 drives the transport belt e1, having lugs for advancing the tins 4E2.

The operation of the machine is as follows: When the operator has placed the tins 6 and 7 onto the disks 4 and 5 respectively, he depresses the foot lever 29 which by aid of the members 30, 31, 32 lifts the plungerlike carrier, so that the tins 6 and 7 with their lids 43 lying on them are pressed against the clamping disks 8 and 9 respectively. The tins 6 and 7 will now revolve in the direction of the arrows Figs. 4, 6'and 7. -At the same time, the clutch 36 isengaged by the aid of the members 34 and 35, whereby'on the o'ne'hand the cam disk 19,

and on the other hand by the members 20,

36 37, 38'and 39 the transport belt 41 is driven. The cam disk 19 will first advance the seaming roller carrier 24 so far, that the first seamingroller 27 bears against the lid 43. When thedisk "19 is turned farther,

' the flattening roller 28 comes into contact with the lids or the tins 6 and 7 and finally closes the tins. Then the seaming roller carrier 24 returns under action of its spring in combination with a single slide which reciprocates on a line between the two stations and carries two seaming means, a first seam mg means and a finishing means, arranged one behind the other and working one after the other but acting simultaneously on the cans at both seaming stations passing through them,

2. A seaming machine provided with two seaming stations, each of which comprises a rotary holding chuck and arotary can body support which reciprocate relatively, in combination, with a single slide which reciprocates on a line between the two stations and carries a. pair of first seaming rollers, and a pair of finishing rollers arranged one behind the other and working one after the other but acting simultaneously on the cans at both seaming stations passing through them.

In testimony whereof I have hereunto signed my name this day of July 1914, in the presence of two subscribing witnesses.
